PHP - Organizing Data By Weeks
So I'm calling in data from a DB where each record is associated with a (column) 'start_time', 'no_shows', 'cancelled', and 'attended' I want to go through the results of this SELECT and count the number of no shows, cancellations and attended on a WEEKLY basis (based on the start_time). How can I achieve this?
The user will provide a date range and the DB will select the records based on that date range. Now this date range will then have to be split by weeks and then get the count. I'm totally stuck on the counting by weeks part. This is what I have so far:
// Multidimensional Array with [boolean][week #]
$no_shows_weekly = [
'no_show' => [],
'week' => []
];
$cancelled_weekly = [
'cancelled' => [],
'week' => []
];
$attended_weekly = [
'attended' => [],
'week' => []
];
foreach($result as $r) {
$start_time = new DateTime($r['start_time']);
if($r['is_no_show'] == 0 && $r['is_cancelled'] == 0) {
array_push($attended_weekly['attended'], 1);
array_push($attended_weekly['week'], date_format($start_time, "W"));
}
else {
array_push($attended_weekly['attended'], 0);
array_push($attended_weekly['week'], date_format($start_time, "W"));
}
array_push($no_shows_weekly['no_show'], $r['is_no_show']);
array_push($no_shows_weekly['week'], date_format($start_time, "W"));
array_push($cancelled_weekly['cancelled'], $r['is_cancelled']);
array_push($cancelled_weekly['week'], date_format($start_time, "W"));
}
echo json_encode(array(
'success'=> 1,
'msg'=>
array(
'No Shows' => $no_shows_weekly,
'Cancellations' => $cancelled_weekly,
'Attendend' => $attended_weekly
)
));
Any suggestions or help is greatly appreciated! Similar TutorialsI'm looking for a method that will return the date for the next 2 weeks in php. I can pull the date but I'm not sure about adding to the date. Can anyone point me in the correct direction? Here is my code: <?php //input will be start date $startdate=0; function getMondays($day,$month,$year,$i,$end){ $x = 7; $add=0; for($i; $i<$end; $i++){ $add++; //This will get the first set of Mondays //store it inside an array //time stamp 11 pm GMT on date $array[$i] = date('U', mktime(0, 0, 0, $month, $day+$counter, $year)); //$firstDay = date('d/m/y', mktime(0, 0, 0, $month, 4+$counter, $year)); $counter = $x * $add; } return $array; } This gets the four weeks following the date set and store it in an array: $Weeks = getMondays(04,04,2011,0,5); Each slot is the equivalent of a week e.g. week 1, week 2, week 3, week 4,week 5 //perform equivilence test if($week1==$currentdate || $currentdate<=$week2){ //for all week 1 stick the following sentence echo "data for week 1"; } if($currentdate>$week2 && $currentdate<=$week3){ //for all week 2 stick the following sentence echo "data for week 2"; } if($currentdate>$week3 && $currentdate<=$week4){ //for all week 3 stick the following sentence echo "data for week 3"; } if($currentdate>$week4 && $currentdate<=$week5){ //for all week 4 stick the following sentence echo "data for week 3"; } if($currentdate==$week5){ //where d/m/y = the date on week 5. //will now become week 1 data getMondays(d,m,y,0,4); } Now depending on which week it is, a set data is displayed which is hardcoded. Now what I want to do is to reset the array on week 4 (for the new month), without the array being repopulated with the old date: $Weeks = getMondays(04,04,2011,0,4); everytime the script is run. How do I do this? I have the following code: Code: [Select] //DETERMINES ASL POLICY if ($perfRow['ASL']=='ToArrange'){ $ASLdate = $perfRow['startDateTime']; $ASLconfirm = strtotime($ASLdate-'21 days'); echo "<!--[ASL=ToARRANGE--><p>An ASL Interpreted performance of this event is offered on".date("l, F j",strtotime($perfRow['startDateTime']))." at ".date("g:i a",strtotime($perfRow['startDateTime'])).".<br />Please contact me by ".date("l, F j",strtotime($ASLconfirm))." to confirm this service.</p>"; }What I need is that if the ASL is "To be Arranged" there is a date that lists for $ASLconfirm that is three weeks prior to $ASLdate. The code above gives me the following: Quote An ASL Interpreted performance of this event is offered on Friday, September 28 at 7:30 pm. Please contact me by Wednesday, December 31 to confirm this service. As you can see from the output the December date is NOT three weeks prior to the September date. Where did I go wrong in my coding? I have a test database set up that I am working on. Right now, just some names like so firstName lastName companyName I have used phpmyadmin to insert names in the database. Right now just three names are inserted. One first and last name, one first name and one company name I am getting the results back in an associative array. How can I echo out the information with the break tag, or one field at a time? if I use a break tag, then the loop adds in extra blank lines when it gets to the first name and it's null. Can I test for null values and do it that way? I am a beginner so I have no idea what I am doing. Code: [Select] $result = $mysql->query("select * from names") or die($mysql->error); if($result){ while($row = $result->fetch_assoc()){ $name = $row['firstName']; $lastName = $row['lastName']; $company = $row['companyName']; echo $name . " "; echo $lastName . " "; echo $company . " "; } } I have two related websites which utilize the same database: Main website for public use. Admin website for administration purposes.Currently, I have both located in /var/www/combined-app which is a single git repository and contains the following: /var/www/combined-app/ public/ public-admin/ src/ main/ admin/ vendor/ composer.json bootstrap.php Alternatively, I could have done the following: /var/www/combined-app/ main/ public/ src/ vendor/ composer.json bootstrap.php admin/ public/ src/ vendor/ composer.json bootstrap.php Or maybe something else all together? Is one approach typically better than the other? If so, please provide reasons why. If my second example, would you recommend separate git repositories for main and admin? Thanks Hi Everyone,
Someone is asking me a bit of help on a website, I know a bit php and HTML5, I would like to know what would be the best of doing this please:
1)I need to create 2 big buttons, according to the choice of the buttons a different dropbox menu with towns will showup.
2)When the user chooses one of the town, in any drop down, I would like to show a different DIV with content in it.
Here is a practical example:
BUTTON A BUTTON B
if Button A is pressed, show dropdown menu A
if BUTTON B is pressed, show dropdown menu B
If town 1 from dropdown menu A is chosen show DIV 1
If town 2 from dropdown menu A is chosen show DIV 1
If town 3 from dropdown menu A is chosen show DIV 2
If town 4 from dropdown menu A is chosen show DIV 3
If town 5 from dropdown menu A is chosen show DIV 1
If town 1 from dropdown menu B is chosen show DIV 6
If town 2 from dropdown menu B is chosen show DIV 5
If town 3 from dropdown menu B is chosen show DIV 5
If town 4 from dropdown menu B is chosen show DIV 6
If town 5 from dropdown menu B is chosen show DIV 4
How to do this without reloading the page please?
Thank you,

so is it impossible if I have a users folder and a messaging folder located in the same folder. To have a script in the users folder reading from the messaging folder from a script in the messaging folder i thought i could just do this to read the users folder but apparently not Code: [Select] <? require("users/menu.php"); ?> hello dear php-experts, well today i have a question regarding the organizing photos in flickr -favs how to do that ? i have 1500 favorites. now i want to organize them into certain " subfolders " or directories question: is this possible? any ideas - i look forward note: i have seen that i am able to download all favs automatically _ great thing but that is another story. I have a file upload script that will eventually process a ton of files. I would like to upload them into sub-directories according to what year, month, and day they are uploaded.
A typical tree should look like this:
attachments/
--/2014
-----/January
--------/01
--------/02
--------/03 , etc.
-----/February
--------/01
--------/04
--------/09
--------/18
--------/20, etc
-----/March, etc
--/2015, etc.
So a file called image.jpg uploaded on 10/31/2014 would have a URL of attachments/2014/October/31/image.jpg. I understand that every time a file is uploaded, the script would have to detect through FTP whether or not folders for the year, month, and day exist, and if they don't create them. My problem is that I have no idea what the logic of this script would be. What order should I do things in? Is there a way to use maybe foreach to detect/create the folders? Any input would be appreciated.
I am refactoring entire collective scattered SQL from my legacy codebase, and into separate classes, and looking for some structure to put it into. Right now I have folders effectively called `DataFromDB` - contains classes that accepts whatever parameters are given, and returns pure data back to the user `DAO` - Data Access Object, which takes that raw data from DB and makes sense out of it and prepares it for consumption by the model/business logic layer objects. That is:
- src (folder)
|- DAO (folder)
| - ProductADAO (classes - take data in, return consumable objects out)
| - ProductBDAO
| - ...
| - ProductZDAO
|- DataFromDB (folder)
| - ProductAData (classes - contain methods to query pure result sets from DB)
| - ProductBData
| - ...
| - ProductZData
Whenever I need to make a new SQL or refactor an old one I do this:
What is this SQL doing? Is it operating on `SomeObjectX`? If yes, find/create class called `ObjectX`, and add a method to it, extracting pure data from DB, put it into `DataFromDB` folder.
Write the `DAO` object if needed to transform data into a consumable object.
Use the object as is in my code.
Does this look like a good strategy? Is there a better one?
My problem with this one is that before (now) all the SQL is tightly coupled and is included into the multiple business classes. Using the above strategy will mean I am to be creating many many classes, a lot of classes, most likely one for every few SQL statements.
The pros is that it seems like I will achieve a level of code modularity that I wanted.
Am new here - looks like a great foru! I would sincerely appreciate any help anyone can give me. I have been trying to solve my problem for hours and I am not having any luck, so I thought I would post and see if anyone can help. I am very stuck and am not making much progress on this project, and I am certain the answer is very simple. I am constructing a form to collect data for a specialized purpose. The form and program actually work for its intended function, but I am trying to enhance the user experience by preventing customers from having to reenter all of their data should there be a problem with any of the data submitted. I have been able to do that with the contact form portion, but what I am having trouble with is the portion which has as many as 400 possible entries. So, in a nutshell, if the customers contact data is incomplete or in error, the form will ask them to return to the page and correct things. The previous data entered has been saved in the session and the input value will equal the previous entry. i.e. <tr> <td align="right" class="infoBox"><?php echo ENTRY_EMAIL_ADDRESS; ?></td> <td align=left><?php echo "<input type=text name='cemail' value=\"$cemail\" size=35 maxlength=35>" ?></td> </tr> Works perfectly, all well and good there. On the other 400 more or less entries, I am having a difficult time tweaking the string concatenation to work to achieve similar results. There are 4 columns each with $points entries asking for a dimension in either feet or inches. The <input name=> is one of ptaf,ptai,ptbf,ptbi, appended programatically with the corresponding row number or data point. i.e. "ptaf1", "ptai1", etc... This is produced by the example below and works perfectly also. <?php { $points=100; $i=1; while ($i <= $points) {echo ' <tr><td align="center" width="6"><b> ' .$i . '</b></td> <td align="right" NOWRAP>A' .$i . ' (ft) <input type="text" name="ptaf'.$i.'" size=4 maxlength=3> </td> <td align="right" NOWRAP>A' .$i . ' (in) <input type="text" name="ptai'.$i.'" size=4 maxlength=4> </td> <td align="right" NOWRAP>B' .$i . ' (ft) <input type="text" name="ptbf'.$i.'" size=4 maxlength=3> </td> <td align="right" NOWRAP>B' .$i . ' (in) <input type="text" name="ptbi'.$i.'" size=4 maxlength=4> </td> '; $i++; } } ?> I am trying to add <input value=$ptai.$i> for each field but as I mentioned I am not having any luck. It seems as if I have tried every combination imagineable, but still no luck. My head is spinning! The closest I seem to have gotten was with this: <td align="right" NOWRAP>A' .$i . ' (ft) <input type="text" size=6 maxlength=3 name="ptaf'.$i.'" value="' . "$ptaf" . $i . '" ></td> But line 17 for example returns this: <input type="text" value="17" name="ptaf17" maxlength="3" size="6"> To recap, I am trying to have the value set to whatever the customer may have entered previously. Again, I would most appreciate any help anyone can give me. If you need clarification on anything please let me know. Thanks AJ Hello to all, I have problem figuring out how to properly display data fetched from MySQL database in a HTML table. In the below example I am using two while loops, where the second one is nested inside first one, that check two different expressions fetching data from tables found in a MySQL database. The second expression compares the two tables IDs and after their match it displays the email of the account holder in each column in the HTML table. The main problem is that the 'email' row is displayed properly while its while expression is not nested and alone(meaning the other data is omitted or commented out), but either nested or neighbored to the first while loop, it is displayed horizontally and the other data ('validity', 'valid_from', 'valid_to') is not displayed.'
Can someone help me on this, I guess the problem lies in the while loop? <thead> <tr> <th data-column-id="id" data-type="numeric">ID</th> <th data-column-id="email">Subscriber's Email</th> <th data-column-id="validity">Validity</th> <th data-column-id="valid_from">Valid From</th> <th data-column-id="valid_to">Valid To</th> </tr> </thead> Here is part of the PHP code:
<?php
while($row = $stmt->fetch(PDO::FETCH_ASSOC))
{
echo '
<tr>
<td>'.$row["id"].'</td>
';
while ($row1 = $stmt1->fetch(PDO::FETCH_ASSOC)) {
echo '
<td>'.$row1["email"].'</td>
';
}
if($row["validity"] == 1) {
echo '<td>'.$row["validity"].' month</td>';
}else{
echo '<td>'.$row["validity"].' months</td>';
}
echo ' <td>'.$row["valid_from"].'</td>
<td>'.$row["valid_to"].'</td>
</tr>';
}
?>
Thank you. Hi, after banging my head against the wall for a while thinking this would be a simple task, I'm discovering that this is more complicated than I thought. Basically what I have is a link table linking together source_id and subject_id. For each subject there are multiple sources associated with each. I had created a basic listing of sources by subject... no problem. I now need a way of having a form to create an ordered list in a user-specified way. In other words, I can currently order by id or alphabetically (subject name lives on a different table), but I need the option of choosing the order in which they display. I added another row to this table called order_by. No problem again, and I can manage all of this in the database, however I want to create a basic form where I can view sources by subject and then enter a number that I can use for sorting. I started off looping through each of the entries and the database (with a where), and creating a foreach like so (with the subject_id being grabbed via GET from the URL on a previous script) Code: [Select] while($row = mysqli_fetch_array($rs)) { //update row order if (isset($_POST['submit'])) { //get variables, and assign order $subject_id = $_GET['subject_id']; $order_by = $_POST['order_by']; $source_id = $row['source_id']; //echo 'Order by entered as ' . $order_by . '<br />'; foreach ($_POST['order_by'] as $order_by) { $qorder = "UPDATE source_subject set order_by = '$order_by' WHERE source_id = '$source_id' AND subject_id = '$subject_id'"; mysqli_query($dbc, $qorder) or die ('could not insert order'); // echo $subject_id . ', ' . $order_by . ', ' . $source_id; // echo '<br />'; } } else { $subject_id = $_GET['subject_id']; $order_by = $row['order_by']; $source_id = $row['source_id']; } And have the line in the form like so: Code: [Select] echo '<input type="text" id="order_by" name="order_by[]" size="1" value="'. $order_by .'"/> (yes I know I didn't escape the input field... it's all stored in an htaccess protected directory; I will clean it up later once I get it to work) This, of course, results in every source_id getting the same "order_by" no matter what I put into each field. I'm thinking that I need to do some sort of foreach where I go through foreach source_id and have it update the "order_by" field for each one, but I must admit I'm not sure how to go about this (the flaws of being self-taught I suppose; I don't have anyone to go to on this). I'm hoping someone here can help? Thanks a ton in advance Here's the code that deals with the client side:

session_start();
if(!isset($_SESSION['Logged_in'])){

<?php //testing if data is sent ok echo "<h1>Hello</h1><br>" . $_GET['search']; ?>This is the link I get after sending foo. http://www.family-li...php?&search=foo Is that mean it was sent, but I'm not processing it correctly? I'm new to the whole AJAX thing. I have two tables. Table Name:Users Fields: User_name user_email user_level pwd 2.Reference Fields: refid username origin destination user_name in the users table and the username field in reference fields are common fields. There is user order form.whenever an user places an order, refid field in reference table will be updated.So the user will be provided with an refid Steps: 1.User needs to log in with a valid user id and pwd 2.Once logged in, there will be search, where the user will input the refid which has been provided to him during the time of order placement. 3.Now User is able to view all the details for any refid 3.Up to this we have completed. Query: Now we need to retrieve the details based on the user logged in. For eg: user 'USER A' has been provided with the referenceid '1234' during the time of order placement user 'USER B' has been provided with the referenceid '2468' during the time of order placement When the userA login and enter the refid as '2468' he should not get any details.He should get details only for the reference ids which is assigned to him. <?php session_start(); if (!$_SESSION["user_name"]) { // User not logged in, redirect to login page Header("Location: login.php"); } $con = mysql_connect('localhost','root',''); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("login", $con); $user_name = $_POST['user_name']; $refid = $_POST['refid']; $query = "SELECT * from reference,users WHERE reference.username=users.user_name AND reference.refid='$refid' AND "; $result = mysql_query($query) or trigger_error('MySQL encountered a problem<br />Error: ' . mysql_error() . '<br />Query: ' . $query); while($row = mysql_fetch_array($result)) { echo $row['refid']; echo $row['origin']; echo $row['dest']; echo $row['date']; echo $row['exdate']; echo $row['username']; } echo "<p><a href=\"logout.php\">Click here to logout!</a></p>"; ?> <html> <form method="post" action="final.php"> Ref Id:<input type="text" name="refid"> <input type="submit" value="submit" name="submit"> </html> Say there is a complex opt in process where people start to enter their data but certain questions stop them where they close out of the page. They already entered their data and I feel there is a way to grab it and post it to mysql even though they do not click submit.
How would this be done?
A super simple example (proof of concept) or a link to a tutorial would be very useful.
Edited by brentman, 23 September 2014 - 10:42 AM. This could be PHP or MySql so putting it in PHP forum for now... I have code below (last code listed) which processes a dynamically created Form which could have anywhere from 0 to 6 fields. So I clean all fields whether they were posted or not and then I update the mySQL table. The problem with this code below is that if, say, $cextra was not posted (i.e. it wasnt on the dynamically created form), then this code would enter a blank into the table for $cextra (i.e. if there was already a value in the table for $cextra, it gets overwritten, which is bad). What is the best way to handle this? I'm thinking i have to break my SQL query into a bunch of if/else statements like this... Code: [Select] $sql = "UPDATE cluesanswers SET "; if (isset($_POST['ctext'])){ echo "ctext='$ctext',"; } else { //do nothing } and so on 5 more times.... That seems horribly hackish/inefficient. Is there a better way? Code: [Select] if (isset($_POST['hidden']) && $_POST['hidden'] == "edit") { $cimage=trim(mysql_prep($_POST['cimage'])); $ctext=trim(mysql_prep($_POST['ctext'])); $cextra=trim(mysql_prep($_POST['cextra'])); $atext=trim(mysql_prep($_POST['atext'])); $aextra=trim(mysql_prep($_POST['aextra'])); $aimage=trim(mysql_prep($_POST['aimage'])); //update the answer edits $sql = "UPDATE cluesanswers SET ctext='$ctext', cextra='$cextra', cimage='$cimage', atext='$atext', aextra='$aextra', aimage='$aimage'"; $result = mysql_query($sql, $connection); if (!$result) { die("Database query failed: " . mysql_error()); } else { } Hi, I want to pull data from db, where sometimes all rows and sometimes rows matching given "username". Here is my code:
//Grab Username of who's Browsing History needs to be searched.
if (isset($_GET['followee_username']) && !empty($_GET['followee_username']))
{
$followee_username = $_GET['followee_username'];
if($followee_username != "followee_all" OR "Followee_All")
{
$query = "SELECT * FROM browsing_histories WHERE username = \"$followee_username\"";
$query_type = "followee_username";
$followed_word = "$followee_username";
$follower_username = "$user";
echo "$followee_username";
}
else
{
$query = "SELECT * FROM browsing_histories";
$query_type = "followee_all";
$followed_word = "followee_all";
$follower_username = "$user";
echo "all";
}
}
When I specify a "username" in the query via the url: browsing_histories_v1.php?followee_username=requinix&page_number=1 I see result as I should. So far so good.
Now, when I specify "all" as username then I see no results. Why ? All records from the tbl should be pulled! browsing_histories_v1.php?followee_username=all&page_number=1 This query shouldv'e worked:
$query = "SELECT * FROM browsing_histories";
I can add and delete data from my table. Now I need to be able to change one or more fields in an entry. So I want to retrieve a row from the db, display that data on a form where the user can change any field and then pass the changed data to an update.php program. I know how to go from form to php. But how do I pass the data from retrieve.php to a form so it will display? Do I use a URL and Get? Can I put the retrieve and form in the same program? |
